JOURNAL-BEARING.

Specification of Letters Patent.

Patented Dec. 18, 1906.

Aprlication filed September 10,1906. Serial No. 333.999.

To rail whom it nw/y concern.-

Be it known that I, FRANCIS M. NASH, a citizen of the United States, residing at Duluth, in the county of St. Louis and State of Minnesota, have invented a new and useful Journal-Bearing, of which the following is a specification.

This invention has relation to journal-bearings; and it consists in the novel construction and arrangement of parts, as hereinafter shown and described.

The object of the invention is to provide a two-part bearing for shafts and the like, means being provided upon the lower part of the bearing for holding the said parts spaced from one another and means being provided for bringing the said parts of the bearing together as the journal wears and is reduced in diameter, thus making it possible to provide a fitting journal-bearing as the diameter of the journal is reduced.

In the accompanying drawings, Figure 1 is a transverse sectional view of the bearing, and Fig. 2 is a side elevation of the same.

The bearing comprises the base member 1, which may be suitably attached to a fixed support. The said member 1 is provided with the vertically-extending threaded perforations 2 2, which receive the externallythreaded posts 3. The said posts 3 are of the same length as the vertical thickness of the portions of the base 1, within which the perforations 2 are located. The cap 4 fits over the upper portion of the base 1 and is secured thereto by means of the screws 5 5. The said cap is also provided with the perforations 5, which are located directly above the perforations 2. The said perforations 2 are of greater diameter than the perforations 5. The upper ends of the posts 3 are provided with squared sockets 6. The longest transverse dimension of the said socket 6 is less than the diameter of the perforation 5, located above the same. The inner meeting edges of the base 1 and the cap 4 are provided with recesses within which are located strips of packing 7. As the shaft (not shown) reduces in diameter the end of the wrench 8 is passed through the perforations 5 and inserted into the socket 6 of the post 3. The said posts are thus successively turned and lowered into the perforations 2. Thus the cap 4 is brought into closer proximity with the base 1 and is held in such position by means of the screws 5, which are tightened up.

Having described my invention, what I claim, and desire to secure by Letters Patent, is

1. A ournal-bearing comprising abase and a cap member, there being threaded perfo rations passing through the base member, and posts screw-threaded into said perforations and having at their ends wrench-receiving sockets, the upper ends of said posts supporting the cap member, said cap member having perforations located over the ends of said posts.

2. A hearing comprising base and cap members, there being threaded perforations passing through the base member, and posts screw-threaded into said perforations and being coequal in length with the perforations and supporting the cap member upon their ends, said posts having at their ends adjacent the cap member wrench-receiving sockets, said cap member having perforations located over the ends of said posts.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

FRANCIS M. NASH.
